How is Your Electricity Generated?

Find out which power sources are generated in your state

The following is the state-by-state breakdown of energy production from major sources. This breakdown does not include energy generation from petroleum, geothermal, biomass, or other power sources because these sources make up a minimal percentage of the mix in most states. However, there are some exceptions. Petroleum, for example, accounts for 63% of Hawaii’s energy generation. Total electricity is measured in thousand megawatt-hours.

Which states produce the most coal and natural gas?

Coal has long been considered the “dirtiest” fuel for electricity production, though generators have made great strides in recent years to lessen the environmental impact. In June, 19.3% of the electricity generated in the U.S. came from coal.

Natural gas burns cleaner, but many environmentalists warn that it produces methane. Here are the states that get the largest part of their electricity from natural gas.

The leaders in green energy production

Hydroelectric power is one of the cleanest energy producers. Washington depends heavily on hydroelectric power – one of the reasons the state consistently has one of the lowest average electricity rates by state.

It likely comes as little surprise that California is among the leading solar producers.

States along tornado alley lead the way when it comes to producing electricity generated from wind. But some unlikely candidates also are big producers:

What about nuclear?

Is nuclear power clean or dirty? It depends on your perspective. It produces a far smaller carbon footprint than coal, oil, or natural gas, so in that respect it’s clean. But there’s the problem of what to do with the spent fuel – it’s difficult to overlook that issue.

That said, let’s put nuclear power in its own category.
